dt-bindings: input: iqs7222: Add support for IQS7222A v1.13+

2022-12-31T12:33:08+00:00

[ Upstream commit 97384a65c5e304ccab0477751546f5519d9371c3 ]

IQS7222A revisions 1.13 and later widen the gesture multiplier from
x4 ms to x16 ms; update the binding accordingly.

As part of this change, refresh the corresponding properties in the
example as well.

dt-bindings: input: iqs7222: Correct minimum slider size

2022-12-31T12:33:08+00:00

[ Upstream commit 99d03b54ef8506771c15deb714396665592f6adf ]

The minimum slider size enforced by the driver is 1 or 16 for the
IQS7222C or IQS7222A, respectively.

dt-bindings: input: iqs7222: Reduce 'linux,code' to optional

2022-12-31T12:33:08+00:00

[ Upstream commit ccad486525c49df2fe2e7090990522547dfd2785 ]

Following a recent refactor of the driver to properly drop unused
device nodes, the 'linux,code' property is now optional. This can
be useful for applications that define GPIO-mapped events that do
not correspond to any keycode.

dt-bindings: mfd: qcom,spmi-pmic: Drop PWM reg dependency

2022-12-31T12:32:52+00:00

[ Upstream commit 763ab98687404d924b6612f7c9c8430333d31229 ]

The PWM node is not a separate device and is expected to be part of parent
SPMI PMIC node, thus it obtains the address space from the parent. One IO
address in "reg" is also not correct description because LPG block maps to
several regions.

dmaengine: idxd: Make read buffer sysfs attributes invisible for Intel IAA

2022-12-31T12:32:47+00:00

[ Upstream commit 9a8ddb35a9d5d3ad76784a012459b256a9d7de7e ]

In current code, the following sysfs attributes are exposed to user to
show or update the values:
  max_read_buffers (max_tokens)
  read_buffer_limit (token_limit)
  group/read_buffers_allowed (group/tokens_allowed)
  group/read_buffers_reserved (group/tokens_reserved)
  group/use_read_buffer_limit (group/use_token_limit)

>From Intel IAA spec [1], Intel IAA does not support Read Buffer
allocation control. So these sysfs attributes should not be supported on
IAA device.

Fix this issue by making these sysfs attributes invisible through
is_visible() filter when the device is IAA.

Add description in the ABI documentation to mention that these
attributes are not visible when the device does not support Read Buffer
allocation control.

dt-bindings: visconti-pcie: Fix interrupts array max constraints

2022-12-31T12:32:33+00:00

[ Upstream commit 4cf4b9b70ab2785461190c08a3542d2d74c28b46 ]

In accordance with the way the device DT-node is actually defined in
arch/arm64/boot/dts/toshiba/tmpv7708.dtsi and the way the device is probed
by the DW PCIe driver there are two IRQs it actually has. It's MSI IRQ the
DT-bindings lack. Let's extend the interrupts property constraints then
and fix the schema example so one would be acceptable by the actual device
DT-bindings.

dt-bindings: imx6q-pcie: Fix clock names for imx6sx and imx8mq

2022-12-31T12:32:33+00:00

[ Upstream commit b8a83e600bdde93e7da41ea3204b2b3832a3c99b ]

Originally as it was defined the legacy bindings the pcie_inbound_axi and
pcie_aux clock names were supposed to be used in the fsl,imx6sx-pcie and
fsl,imx8mq-pcie devices respectively. But the bindings conversion has been
incorrectly so now the fourth clock name is defined as "pcie_inbound_axi
for imx6sx-pcie, pcie_aux for imx8mq-pcie", which is completely wrong.
Let's fix that by conditionally apply the clock-names constraints based on
the compatible string content.
